Magneto-thermal evidence of a partial gap at the Fermi surface of UPt_2Si_2
N. Johannsen, S. Suellow, A. V. Sologubenko +2
Motivated by the observation of a giant Nernst effect in URu_2Si_2, the thermoelectric response of the related system UPt_2Si_2 was investigated using thermal and electric transpor…
Nernst Effect in NdBa_2[Cu_{1-y}Ni_y]_3O_{7-δ}
N. Johannsen, Th. Wolf, A. V. Sologubenko +3
In NdBa_2[Cu_{1-y}Ni_y]_3O_{7-δ}, magnetic Ni-impurities suppress Tc but at the same time the pseudogap is strongly enhanced. This unique feature makes it an ideal system to study…
Uniaxial pressure dependencies of the phase boundary of TlCuCl_3
N. Johannsen, A. Oosawa, H. Tanaka +2
We present a thermal expansion and magnetostriction study of TlCuCl_3, which shows a magnetic-field induced transition from a spin gap phase to a Neel ordered phase. Using Ehrenfes…
Magnetoelastic Coupling in the Spin-Dimer System TlCuCl
N. Johannsen, A. Vasiliev, A. Oosawa +2
We present high-resolution measurements of the thermal expansion and the magnetostriction of TlCuCl which shows field-induced antiferromagnetic order. We find pronounced anom…
